Will Smith is back on the silver screen today as the iconic Agent J in ‘Men in Black 3.’

It is the only film of the franchise—which first hit theatres in 1997—to be screened in 3D. In the time-travel plot, Agent J (Smith) travels back to 1969 to save young Agent K (Josh Brolin). “The time jump sequence is the beauty of 3D. That’s how 3D is supposed to be used,” Smith said in a recent interview.
